STEAM TURBINE.

Application filed September 17, 1921. Serial No. 501,242.

To all whom it may concern:

Be it known that I, CLIFTON E. KooNoE,

a citizen of the United States, residing at Coalinga, in the county ofFresno and State of California, have invented new and usefulImprovements in Steam Turbines, of which the following is aspecification.

This invent-ion relates to improvements in steam turbines, the principalobject of which is to devise a turbine which is compact, one

which may be reversed and one which is simple to construct.

Another object of this invention is to devise a turbine wherein there isa minimum number of parts some of which can be readily replaced whennecessary, and a turbine that will assure freedom from mechanicaltroubles incident to complicated machines.

Another object of this invention is to devise a turbine of the characterdescribed which will be very light and compact, with the result that thesame may be used in automobiles and like road vehicles, and a turbinewhich can be readily assembled and disassembled.

Other objects and advantages will be apparent during the course of thefollowing description.

In the accompanying drawings forming a part of this specification and inwhich like numerals are employed to designate like parts throughout thesame,

Fig. 1 is an end elevation of my device.

Fig. 2 is a side elevation of Figure 1.

b Fig. 3 is a detail view of the valve cham- Fig. 4; is a cross-section,taken on the line 1-4 of Figure 5.

Fig. 5 is a cross-section taken on the line 5-5 of Figure 4.

Fig. 6 is a cross-section taken on the line 66 of Figure 4.

Figures 7 and 8 comprise a fragmentary detail view of the ports.

In the accompanying drawings wherein for the purpose of illustration isshown a preferred embodiment of my invention, the numeral 5 designates abase having supports 6 and 7 mounted thereon. These supports serve tosupport the turbine as a whole. The numerals 8 and 9 refer to twosemicircular castings closed at their ends, and forming a cylindricalhousing for the rotors. These castings 8 and 9 are suitably securedtogether as by bolts 10, and are provided with bearings for a shaft 11'centrally'disposed therein. This shaft 11 has keyed thereto rotors 12,13 and 14, which rotors are each provided with a seriesjof buckets abouttheir periphery,said buckets being angularly disposed with respect tothe center line of said rotors,the buckets upon one side of the rotorcontinuing the same angle as the bucket-5' on the opposite side;

Division members 15 and 16 are disposed between the rotors and endplates 17 and 18, and are adapted to abut the outer surface of the endrotors. These division members and end plates are adapted to control thedirection that steam is admitted to the rotors through the medium ofpassages formed therein.

When the turbine is moving in a direction indicated by the arrow ofFigure 4, steam is admitted to the steam chambers 19 and 20, and as thesame are identical, but one will be described.

The steam chamber is formed by an elongated housing 20 bolted to thecastings 8 and 9, and a slide valve 21 is provided therein. This slidevalve is operated in the usual manner by a rod 22, and needs nodescription.

Suitable ports are provided in said valve so that steam entering throughpassage 28 may be controlled to the proper sides of the rotor.

Assuming now that steam is admitted to the chamber 19, the steam willpass as indicated by the rotors through ports 24 and 25 into the endplate 18 and division member 15. After entering the end plate 18, itwill be diverted through the passage 26 to the right hand side of therotor, as shown in Figure 5. The steam entering the division member 15will pass through passages 27 and 28 to the rotors 13 and 1 1. Thissteam will be effective through a quarter of the revolution, from whichpoint the same will escape as through exhausts 29. Steam entering thelower steam chamber of the turbine will follow in exactly the samecourse except that it will exhaust through an exhaust valve 30.

To reverse the engine, the slide valve 21 is moved to the left of thedrawing, as shown in Figure 5, which will result in the steam enteringthe division member 16 through port 31 and end plate 17 through port 82.Steam will then be caused to travel to the opposite sides of each of therotors as will be noted by examining these ports, as shown in Figure 6.

It will thus be seen that I have construct ed a turbine, which has thebuckets angularly disposed with relation to the center line of therotor, and that I control the direction in which the steam is admittedto the rotors by the simple manipulation of slide valves, the sameresulting in steam being admitted to either one side or the oppositesides of the rotors to cause either forward or reverse movement thereof,all of the parts being simple to construct and consequently cheap tomanufacture.

Itis to be understood that the form of my invention herewith shown anddescribed is to be taken as a preferred example of the same, and thatvarious changes in the shape, size, and arrangement of parts may beresorted to without departing from the spirit of the invention or thescope of the subjoined claim. v

Having thus described my invention, I claim:

In a rotary turbine, the combination of castings, steam chambers formedon said castings, slide valvesmounted insaid steam chambers, ports insaid slide valves ports in said castings, a shaft carried by saidcastings, rotors placed on said shaft, division members between saidrotors, ports in said division members, and buckets formed on saidrotors, saidbuckets onthe opposite sides of said rotors being in axialalignment when adapted to receive steam therein for the purpose ofcausing rotation of said rotors in either a forward or reversedirection.

In testimony whereof I afiix my signature.

CLIFTON E. KOONCE.
